Putting the results of pp (or anything outputted to console) into a string

Question

We know

require \'pp\'
a=[\"value1\", \"value2\", \"value3\"]
pp a

pretty prints the array as an output to the console. How do I get that p

Answer 1

string_value = a.pretty_inspect

#pretty_inspect also comes along when you first require 'pp' - See: http://ruby-doc.org/stdlib-2.1.0/libdoc/pp/rdoc/Kernel.html#method-i-pretty_inspect

If you want the version that is outputted to the irb console that is

 string_value = a.inspect

and doesn't have any requires necessary.
